ltviPRGVEMENT IN BRICK-*MACHiNES.

Specification forming part of Letters Patent No. 136,520, dated March 4,1873.

To all whom it may concern:

Be it known that I, DONALD J. IRWIN, of Noble, in the county of Richlandand in the State of Illinois, have invented certain new and usefulImprovements in Brick-Machine; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters of reference marked thereonmaking a part of this specification.

The nature of my invention consists in the construction and arrangementof a brick-machine, as will be hereinafter more fully set forth. I.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan view, the sweep being removed; and Fig.2, a sideelevation ofmy entire machine. Fig. 3 is a plan view of the mud-millwith the mixing-mechanism removed, showing the entrance to the feederbelow. Fig. 4 is a plan view of the mold-wheel or case-bearer. Fig. 5 isan inverted or bottom View of the mud-mill, showing the feeder and themechanism connected therewith. Fig. 6 is a section through the line 1 2,Fig. 5; and Fig. 7 is a perspective view of the loading apparatus.

A represents the frame-work of my brickmachine, which may be constructedin any suitable or convenient manner to contain the various workingparts of the machine. Upon the frame-work A is located the mud-mill B,which is circular in form and of any suitable dimensions. Within themill B is the mixing mechanism, consisting alternately of stationary andrevolving plates, each plate forming a series of curved cutting-blades,marked, respectively, O and (J. The revolving plates are attached on acentral upright shaft, a, which passes through suitable bearings abovethe mill, and its upper end firmly attached to the sweep E, to whichthehorses are to be attached for operating the machine. The stationarycutting-blades G and the revolving blades 0 are curved. in oppositedirections, as shown in Fig. 1, and when in operation the material fromwhich the bricks are to be made is thoroughly mixed and forced throughthe aperture 12 in the bottom of the mill into the cylindrical conductorD attached underneath the mill. Within this conductor the feeder isplaced, said feeder consisting of a central shaft, 01, having teeth orwings e 6 arranged spirally on said shaft, and working between similarstationary teeth or wings, e e, attached to the inside of the conductorD, the effect of which is to feed the mud or clay through the conductorand out through the mouth f, and deposit the same in the molds.- On thelower end of the central shaft to, below the bottom of the mill and atthe side of the conductor 1), is attached a pinion, g, which meshes witha cog-wheel, 8, attached to the upper surface of a circular wheel orturn-table, G, which is pivoted on a part of the frame A, and thusreceives its rotary motion. On the outer edge of the turn-table G, atregular intervals, are pivoted arms H, to the outer end of each of whichis pivoted a carrier, I, to receive and carry the molds from the loaderto the place of deposit, the turntable G thus forming the mold-bearer.Along the inner edge of each carrier I is an upward-projecting flange,t, and at the rear end is a stop, 70, against which the mold is to rest.To the pivot of each arm H is attached a crank, m, extending under the.case-bearer G, as shown in Fig. 4. Below the mold-bearer G, on theframe, are arranged two friction-rollers, a and a, and above thecasebearer, on the frame, are arranged two other friction-rollers, p 1).

As the mold-bearer G revolves, the inner edge of each carrier I strikesthe roller p, which brings the carrier in proper position to receive themold from the loading-mechanism, the arm H being at about the same timedrawn or turned partially inward by the crank on striking the roller a.As the bearer revolves,

the rollers a and p, acting upon the crank m and carrier I, throw thearm and carrier into the proper position for the mold to enter betweenthe guides r 2' arranged on each side of the mouth f, as shown in Fig.5, where the mold is filled, and from whence it passes onto areceiving-table, J, revolving on its center. While the mold is passingbetween the guides r r, the arm H and carrier I are drawn outward fromthe mold-bearer, and are then by the rollers to and 1) brought intoposition again to receive another mold from the loader. At the front endof the mouth 1 is a circular cutter or trimmer, K, revolved by means ofsuitable bevel-gearing from the feed-shaft d, and this shaft is revolvedby a pinion, s, on its end, gearing with the crown-wheel h on the upperface of the mold-carrier G.

The loader is constructed in the following manner: L represents astationary frame, having along its sides on the inner side inclinedstepbars t, upon each step of which is secured a spring, 11. Within thisstationary frame is a sliding plate, M, and on top of the same is asliding frame, N, having inclined step-bars t on the sides,corresponding with the step-bars on the stationary frame. Below thestationary frame L is pivoted a lever, O, the upper end of which isconnected with the rear end of the sliding frame N by a link, w. Betweenthe upper end and the pivot-point of the lever O a link, to, connectswith the sliding plate M, so that when the lever O is turned on itspivot the frame N will move faster or further than the plate M. Thelower end of the lever O is, by rods w and :10, connected with twoelbowlevers, P and 1 respectively. These levers are operated by means ofpins or projections 3 attached adjustably on the under side of themold-bearer G, one for each of the carriers. These pins or projectionsin rotation strike the lever P, moving the plate M and frame N forwardto deposit one mold on the carrier, and the pin then strikes the otherlever P, which draws said parts back to their former position. A seriesof molds, R, are placed on the stationary step-bars t, and by themovement of the plate and sliding frame they are moved downward orinward on the same, one mold being deposited on a carrier at eachmovement inward of said plate and frame.

The molds R are constructed as shown in Fig. 1, the front end beinginclined and provided with a hinged apron, z. The mold is also providedwith transverse partitions a, which are pivoted at their lower ends, andon one side there is a crank, I), attached to or formed on the pivot.The partitions a should be thrown down when the mold is placed on thecarrier, and just as each space is under or opposite to the mouth f thecrank b is turned by a roller, d, shown in Fig. 5, to raise thepartition.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The revolving mold-bearer G, provided with a series of arms, H,pivoted at regular intervals to its outer edge, and each arm having acarrier, I, pivoted to its outer end, sub- :tantially as and, for thepurposes herein set 'orth.

2. The carrier I, pivoted to the outer end of the pivoted arm H andprovided with the flan get and the stop 70, substantially as and for thepurposes herein set forth.

3. The combination of the crank m on the pivot of the arm H and therollers n and n, for the purposes herein set forth.

4. The combination of the flange t" on the carrier I and the rollers 19and p, for the purposes herein set forth.

5. The combination of the arm H with crank m on its pivot, the carrier Iwith flange t, and the rollers n n and p p all substantially as and forthe purposes herein set forth.

6. The loading mechanism, consisting of the stationary frame L withstepbars t t and springs 'U o, the movable plate M, and the movableframe N with step-bars t t, substantially as and for the purposes hereinset forth.

7. The combination, with the loader, of the lever 0, links 20 w, rods ww, levers P P, and pin or projection 3 on the mold-carrier G,substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this29th day of October, 1872.
